LVCHANGE(8) LVCHANGE(8) NAME lvchange - change attributes of a logical volume SYNOPSIS lvchange [--addtag Tag] [-A/--autobackup y/n] [-a/--available y/n/ey/en/ly/ln] [--alloc AllocationPolicy] [-C/--contiguous y/n] [-d/--debug] [--deltag Tag] [--resync] [-h/-?/--help] [--ignorelocking- failure] [--ignoremonitoring] [--monitor {y|n}] [-M/--persistent y/n] [--minor minor] [-P/--partial] [-p/--permission r/w] [-r/--readahead ReadAheadSectors] [--refresh] [-t/--test] [-v/--verbose] LogicalVol- umePath [LogicalVolumePath...] DESCRIPTION lvchange allows you to change the attributes of a logical volume including making them known to the kernel ready for use. OPTIONS See lvm for common options. -a, --available y/n/ey/en/ly/ln Controls the availability of the logical volumes for use. Com- municates with the kernel device-mapper driver via libdevmapper to activate (-ay) or deactivate (-an) the logical volumes. If clustered locking is enabled, -ae will activate exclusively on one node and -aly will activate only on the local node. To deactivate only on the local node use -aln. Logical volumes with single-host snapshots are always activated exclusively because they can only be used on one node at once. -C, --contiguous y/n Tries to set or reset the contiguous allocation policy for logi- cal volumes. It's only possible to change a non-contiguous logi- cal volume's allocation policy to contiguous, if all of the allocated physical extents are already contiguous. --resync Forces the complete resynchronization of a mirror. In normal circumstances you should not need this option because synchro- nization happens automatically. Data is read from the primary mirror device and copied to the others, so this can take a con- siderable amount of time - and during this time you are without a complete redundant copy of your data. --minor minor Set the minor number. --monitor y/n Controls whether or not a mirrored logical volume is monitored by dmeventd, if it is installed. If a device used by a moni- tored mirror reports an I/O error, the failure is handled according to mirror_image_fault_policy and mirror_log_fault_pol- icy set in lvm.conf. --ignoremonitoring Make no attempt to interact with dmeventd unless --monitor is specified. Do not use this if dmeventd is already monitoring a device. -M, --persistent y/n Set to y to make the minor number specified persistent. -p, --permission r/w Change access permission to read-only or read/write. -r, --readahead ReadAheadSectors Change read ahead sector count per logical between 2 and 120. For compatability with LVM1 only. Ignored by LVM2. --refresh If the logical volume is active, reload its metadata. This is not necessary in normal operation, but may be useful if some- thing has gone wrong or if you're doing clustering manually without a clustered lock manager. Examples "lvchange -pr vg00/lvol1" changes the permission on volume lvol1 in volume group vg00 to be read-only. SEE ALSO lvm(8), lvcreate(8), vgchange(8) Sistina Software UK LVM TOOLS LVCHANGE(8)
